Patented Feb. 9, 1932 UNETED gTATES WALLACE FRED WALKER, F LENTON, NOTTINGHAM, ENGLAND BUILDING BRICK OR BLOCK Application filed September 17, 1931, Serial No. 563,423, and in Great Britain May 28, 1930.

My invention relates to building bricks, and more particularly relates to bricks of the type which, when placed in position in a wall or the like, form continuous perpendicular and horizontal air vents through the centre thereof, and resides in forming such bricks of this type with longitudinal strips extending sub stantially across on the inner portion of their upper surfaces and adapted to interlock with a corresponding recess on the lower surfaces so that, when the wall or other structure is in course of erection, and one brick placed over the other, the strip of one brick fits into the recess of the other, thereby forming an interlock, and, at same time preventing any mortar falling into the air vents, and forming a damp-proof structure and provided with recesses at each end, the centre portion being sloped in a downward direction towards the end recesses so that no moisture will lodge on the brick, but rundown the incline into the recesses.

The face of the wall, or other structure is similar in every respect to that built of ordinary bricks, and can be built to any thickness desired, and the building of same with such bricks is as easy as building with ordinary bricks.

in order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which Figure 1 is a top plan view showing the improved building unit.

Figure 2 is a longitudinal section taken on the line 2-2 in Figure 1, and

Figure 3 is an end view of the building unit.

Referring more particularly to the drawings, the improved building unit is constructed of two spaced apart bricks 5 and 6 having a narrow connecting piece 7 joining the intermediate portions only of the adj acentfaces of the two bricks and providing at each end of the connecting piece 7 a single wide and deep recess 8 opening through the upper and lower portions of the unit.

The intermediate connecting piece 7 is formed with downwardly and outwardly sloping upper walls 9 including in opposite directions to said recesses 8. Longitudinal strips 10 are also provided projecting upwardly beyond the upper plane of the unit and joining with the inner surfaces of the two bricks. Such strips 10 overhang the recesses 8.

The center connecting piece 7 is formed with a vertical hole 11 therethrough, and the lower portion of the connecting piece 7 is oifset upwardly from the lower surfaces of the two bricks 5 and 6 in order to provide a continuous horizontal channel all along the building units when laid up in a wall.

The sloping surfaces 9 will cause any moisture to be directed down into the recesses 8 and will prevent any accumulation of the moisture on such surfaces. The holes 11, and recesses 8, provide continuous clear passages for the air. When the bricks are put upon one another or laid upon one another, the strips 10 will fit into the space between the two bricks 5 and 6, of an upper unit, and the recesses 8 and upward offsetting of the lower part of the center portion 7 will permit of this interfitting and interlocking of the strips 10 with lower portions of the upper unit.

What I claim. is

1. An improved building unit comprising two spaced apart bricks, a narrow connecting piece joining the intermediate portions only of the adjacent faces of the two bricks, and providing at each end of said connecting piece a single wide and deep recess opening through the upper and lower portions of the unit, said connecting piece having downwardly and outwardly sloping upper walls inclining in opposite directions to said recesses, and longitudinal strips projecting upwardly from the opposed inner surfaces of the two bricks and overhanging said recesses.

2. An improved building unit comprising two spaced apart bricks, a narrow connecting piece joining the intermediate portions only of the adjacent faces of the two bricks, and U providing at each end of said connecting piece a single wide and deep recess opening through the upper and lower portions of the unit, said connecting piece having downwardly and outwardly sloping upper walls inclining in opposite directions to said re- 1m cesses, and longitudinal strips projecting upwardly from the opposed inner surfaces of the two bricks and overhanging said recesses, said center piece having a substantially vertical hole therethrough and being offset upwardly from the lower surfaces of the two bricks in order to provide a continuous horizontal channel all along the building units when laid up in a wall.

WALLACE FRED WALKER.
